Yes but at the same time you have to look for the range and domain
Answer:
Lowest Price - Store B
Middle Price - Store C
Highest Price - Store A
Step-by-step explanation:
Store A Price - $22.50
25 x 0.1 = 2.5
25 - 2.5 = 22.5
Store B Price - $21.60
27 x 0.2 = 5.4
27 - 5.4 = 21.6
Store C Price - $22.1
26 x 0.15 = 3.9
26 - 3.9 = 22.1
Decibel is directly proportional to number of cars passing the point. That is,
69 db ----- 139 cars
x db ----- 17 cars
x = number of cars passing the point per minute on a weekend.
Then,
x= (69*17)/139 = 8.43 db ≈ 8 db
